3 Claims. (Cl. 112-137) This invention relates to sewing machineattachrnents, and more particularly to a sewing machine attachment knownas a binder in that it is employed for sewing a binding at the edge of apiece cf material, so that the latter will be embraced by the bindingtape or strip. In general, these devices comprise a frame of some kindto which is secured an adapter by which the device may be secured to thepresser bar of the sewing machine, and mounted upon the frame is anelement termed a scroll, having slots of various lengths to accomrnodatebinding strips of Various widths and a central passageway to receive thematerial, the scroll being so constructed that the binding strip or tapewill be folded about the edge of the material disposed in the centralslot.

In Order to properly align the binding strip with the edge of thematerial and also with the needle opening, the frarne of the device issometimes constructed so that it is adjustable laterally with respect tothe adapter, and therefore with respect to the presser bar and needlebar of the sewing machine. As the scroll is carried by this frame it isalso laterally adjustable With respect to the needle opening.

The scroll is usually mounted in an inclined position with respect tothe frame, and if the scroll is adjusted laleraliy of the frame, i: willbe apparent that the adjustment does not take place about the axis ofthe scroll, or in a plane parallel to the axis of the scroll. In thepresent construction the scroll is mounted upon an auxiliary frame whichis so connected to the main frarne of the device that it may be adjustedangularly so that the adjustment of the scroll will take placesubstantially about the longitudinal axis of the scroll itself. Thisauxiliary frame supports the scroll and is provided With an arcuate slotthrough which are received fastening members connected to the main frameso that the auxiliary frame is frietionally hold in place in any ositionof angular adjustment, as permitted by the arcuate slot.

One object of the present invention is to provide a binding altachmentfor sewing machines, of novel and simple construction.

A still further object of the invention is to provide a bindingattachrnent for sewing machines, in which the scroll 1's carried on anauxiliary frame adjustably comnected to the main frarne of theattachment.

A still further object of the invention is to provide a bindingattachment for a sewing machine, in which the scroll is mounted on anauxiliary frame secured to the rnain frame so that it may be angularlyadjusted, the adjustment taking place substantially about the axis ofthe scroll.

T0 these and other ends the invention consists in the novel features andcombinations of parts to be hereinafter described and claimed.

T0 illustrate a preferred embodirnent of my invention I have shown abinding attachrnent for sewing machines, including a main frame whichcomprises a plate 10 to which is adjustably secured the usual adapter 11which may be secured to the presser bar of the sewing machine. Theadapter comprises a body member of L-shaped formalion, and the base 12thereof underlies a portion of the plate 10. This portion of the frameis provided With an elongated slot 13 through which extends a rivet 14so that when the adapter is secured to the presser bar the plate 18 maybe adjusted laterally with respect to the adapter and presser bar andneedle bar of the machine. Below the head of the rivet 14 and above theplate 10 is a bowed spring 15 bearing upon the plate so as tofrictionally hold the frame in any position of adjustrnent, and movementof the frame laterally may be conveniently efiected by means of thefingerpiece 16 upstanding from the plate. The latter is also providedwith an elongated slot 17 adaptecl to register with the needle opening18 in the part 12 of the adapter.

The fralne includes an upwardly and rearwardly inclined portion 20 atthe rear end of the plate 10, and it is to this portion that theauxiliary frame which carries the scroll is secured. This auxiliaryfrarne cornprises a forward end portlon 21 which lies flatly upon theportion 20 of the main frarne N. Extending rearwardly from the portion21 is an arm which comprises a substantially horizontal portion 22 and adownwardly and rearwardly inclined portion 23. Projecting laterally fromthe part 23 is a downwardly offset portion 24 upon which the scroll 25is carriecl.

The scroll may be cf usual form and in this instance is provided with aplurality of slots 26 of different length so as to accommodate bindingstrips 0f different Width. The scroll is tapered in size from its rearend toward its forward end, as is usual, both ends being open so thatthe material may be received at one end and may emerge at the other end.

The forward or body portion 21 of the auxiliary frame extends over theforward portion 20 of the main frarne, as stated, and this portion ofthe auxiliary frarne is provided With an arcuate slot 27. A rivet 23 issecured to the portion 20 of the main frame and passes through the slot27. Under the head of this rivet is a spring Washer 29 so that theauxiliary frame Will be frictionally held in any position to which it isadjusted. A guide pin 30 is also secured to the part 20 of the mainframe and received in the slot 27, so that the auxiliary frame will beguided and limited in its arcuate rnovements With respect to the mainframe.

It may ba noted that the scroll is supported upon the auxiliary frame atsuch an angle that its axis is substantially at right anglcs 10 theportion 21 of this frame, and it may also be noted that the arcuate slot27 is described substantially abont the axis of the scroll as a center.Therefore adjustrnent cf the auxiliary frame as permitted by the arcuateslot 27 will be substantially about the axis of the scroll, and theposition of the latter with respect to the needle opening Will bechanged only to a slight extent, if at all. The adjustment, however,will change the position of the binding strip With respect to thematerial so that the upper and lower edges of the binding strip may bepositioned as desired with respect to the material.

While I have shown and described a preferred embodiment of my invention,1't will be understood that it is not to be limited to all cf thedetails shown, but is capable 3 of mo di fi c atigq a1;d vapria t iopwithin the spirit of the invention and within the scope of the claims.
